METHODE POUR FORMER UNE MONTURE DE LUNETTES INCORPORANT UN AIMANT

METHOD FOR FORMING A SPECTACLE FRAME HAVING A MAGNET MEMBER

Abrégé français

La présente invention a pour objet une méthode pour former une monture de lunettes comportant un ou plusieurs aimants incorporés dans la monture sans préjudice au niveau de l'apparence de la monture. Un ou plusieurs éléments magnétisables sont assemblés sur la monture de lunettes avant d'être magnétisés. Les éléments magnétisables sont magnétisés afin de permettre aux éléments magnétisables d'être magnétisés sans causer préjudice à l'apparence de la monture de lunettes.

Abrégé anglais

A method may form a spectacle frame having one or
more magnets engaged in the spectacle frame without
spoiling the outer appearance of the spectacle frame.
One or more magnetizable members are engaged in the
spectacle frame before the magnetizable members are
magnetized. The magnetizable members are then
magnetized for allowing the magnetizable members to be
magnetized without damaging the outer appearance of the
spectacle frame.

13ACKGROUND OF T1-IE INVENTION
1. Field of the Invelltio1-
05 The present invention relates to a method, and
more particularly to a method for forming a spectacle
frame having one or more mag1lets for attaching an
auxiliary fral11e.
2. Description of the Prior Art
Typical eyeglasses may include one or more magnets
for attaching an auxiliary frame or for attaching
auxiliary lenses. Two examples of the eyeglasses are
disclosed in US Patent No. 5,416,537 to Sadler and
5,568,207 to Chao. The spectacle frame is required to
be excavated ~ith one or more ho]es for engaging with
the magnets. I~owever, the engagement of the magnets may
clamage the outer appearance, particularly the painting
ol the spectacle frame. In addition, the magnets have
difrerellt colors from that of the spectacle frame such
that the magnets may spoil the outer appearance of the
beautiful spectacle frame.
The present invention has arisen to mitigate
an(l/or obviate the afore-descri~)ecl disadvantages of the
convelltiollal eyeglasses.
SUMMARY OF THE INVRNTION
The primary objective of the present invention is
l-o provide a methocl for forming a spectacle frame

CA 0223~897 1998-07-29
llaving magl1ets and for ailowil1g the magl1ets to be
engaged in the spectacle frame without damaging the
outer appearance of the spectacle frame.
In accordance with one aspect of the invention
05 thele is provided a method for forming a spectacle
frame having one or more magnets engaged in the
spectacle frame the method comprises engaging one or
more magneti7able members in the spectac]e frame before
the magneti7.ab]e meml)ers are magnetized or after the
magnetizable members have been magnetized. The
magnetizable men1l-ers may be engaged in the spectacle
frame when the spectacle frame is molded or may be
engaged in the spectacle frame by excavating the
spectacle frame with one or more holes. The
magnetizable members are then magnetized for allowing
the magnetizable members to be magnetized without
damaging the outer appearance of the spectacle frame.
Further objectives and advantages of the present
invention wi]l become apparent from a careful reading
of a detailed description provided hereinhelow with
appropriate reference to accompanying drawings.

FIG. 1 is an exploded view of a spectacle frame to
be made by the method in accordance with the present
invention;
FIG. 2 is a cross sectional view taken along lines
2-2 of FIG. 1; and

FIG. 3 is a schematic view il]ustrating the
forrnil1g of the magnets.
DETATLRn DRSCRTPTION OF THE PREFERRED EMBODJMENT
Referring to the drawings, and initially to FIG.
05 1, a spectacle frame in accordance with the present
invention comprises a primary frame 10 for supporting
pl-imary lenses ~0 and an auxiliary frame 20 for
sllpporting au~iliary lenses 91. The primary frame 10
includes one or more magnets 11, 12 for engaging with
the magnets 21 of the auxiliary frame 20 and for
securing the auxiliary frame 20 to the primary frame
1 0 .
Referring next to FIG. 2, one or more magnetizable
members 12, 21 are engaged in the frame 10, 20 when
forming the frame 10, 20 by such as molding process and
before the members 12, 21 are magnetized. The frame 10,
20 may also be excavated with one or more holes for
engaging with the members 12, 21 which are not being
magnetized yet at this moment and which may be secured
to the frame 10, 20 by adhesive material. The frame 10,
20 may then be electroplated and painted such that the
memhers 12, 21 may be suitably embedded in the frame
10, 20. It is to be noted that the frame 10, 20 ancl the
membels 12, 21 may not be suitably electroplated if the
members 12, 21 have already been magnetized. The magnet
m~mbers 12, 21 may attract other particles to the
spectacle frame su(l1 that the spectacle frame may not

CA 0223~897 1998-07-29
b~ rorrlle-l wilh a smooll1 outeJ- appearal1ce after
electroplating process.
Referring next to FIG. 3 the frame 10 20 is then
dispclsed in a magnetizing machine 80 such as an
05 electromagl1etic machine for allowing the magnetizing
machine 80 to magnetize the members 12 21 without
~lamaging the outer appearance of the frame 10 20. The
members 12 21 may thus be secured in the frame 10 20
before they are magnetized and may then be magnetized
w;thout damaging the outer appearance of the frame.
Alternative]y a magnetizable member which has
already magnetized is first engaged in a spectacle
frame. The spectacle frame will not be electroplated
and will be further treated by welding washing
painting ancl drying processes. However the hot
working environment may demagnetize the members 12 21
sucll that the members 12 21 are required to be
magnetized after the frame has been completely treated.
The final magnetizil1g process may further magnetize the
magnetizable members without damaging the outer
appearance of the spectacle frame.
Accordingly the method in accordance with the
preSellt illVellt iOIl may engage the magnets in the
spectacle frame l-efore the magnets are magnetized and
may magnets after the magnets are engaged in the
spectacle frame such that the magnets may be engaged in
the spectacle frame witho-~t damaging the outer

~pp(arance o:f l-he spectac].e frame.
Althougl~ this invellt;.oll has heell described with a
cellain degree of particularity it is to be ullderstood
t:hat the plesellt disclosure has been made by wav of
n5 example only alld that numel-ous changes in the detailed
~ collstructioll and the combillatiorl and arrangement of
parts may be resorted to ~ithout departing from the
spir;t an(l scope of tlle irlventioll as hereinafter
c]aimed.
